The Filament Down Jacket is a lightweight, water resistant and down insulated jacket for activities where a high warmth-to-weight ratio is crucial.

Outdoor Research says:

The 800+ fill power goose down-insulated, ultra-lightweight Filament Jacket features an incredible warmth-to-weight ratio, cutting the chill when worn alone in cool weather and holding in just enough heat as a mid-layer in truly nasty conditions. Its packable, DWR-treated 10D Pertex Quantum GL fabric sheds moisture, further increasing the versatility of this featherweight, year-round down layer.

The Filament Down Jacket is made from Pertex Quantum GL outer shell fabric which is feather-light, downproof, windproof and breathable, with a silk like softness that you won't want to take off! This comfortable jacket is filled with 800+ goose down which gives it an excellent warmth-to-weight ratio. It can be worn on it's own to keep the chill out or as a mid layer to keep the heat in on really cold days.

This lightweight jacket features stretch binding cuffs, a drawcord hem, a good sized chest pocket and two hand warmer pockets for keeping your hands toasty warm. The left pocket can be used as a stuff sack when traveling to save on space in your pack. The Filament Down jacket would be perfect for wearing around the crags belaying, worn as a midlayer for skiing or for just wearing around town. It has got a bit of a shine to it, which might not be everyone's cup of tea, but it's a great lightweight jacket.
